I Put the New L’Oréal Hair Dryer Head-to-Head With the Dyson—Here’s What I Thought (2025)

You’ve probably already heard of the Dyson Supersonic Hair Dryer. It’s renowned for cutting down blow-dry time, protecting scalp health, and offering intelligent attachment recognition. Dyson has long been a top hair styling tool in beauty editor rankings. But now, there’s a new contender in the haircare arena: the AirLight Pro, L’Oreal Professionnel’s first hair dryer. Powered by innovative infrared technology, this addition claims to reduce drying time, reduce energy consumption, and minimize heat damage (a win-win-win in my book).

While both hair dryers promise similar benefits and deliver impressive results, some key differences are worth noting. As these tools are significant investments, I tested them to see if the L’Oréal Professionnel AirLight Pro dryer stacks up to the Dyson. I assessed them across four essential categories—attachments, settings, performance, and overall value—to determine which is the best pick for you.

Max Temp: 302 degrees | Features: 6 styling attachments, infrared light technology, 3 speed, and 4 heat settings | Warranty: 2 years

Who It's For: The Dyson Supersonic is designed for those who dry their hair frequently and are looking for a reliable, versatile hair dryer that caters to all hair types and textures. It’s ideal if you value a user-friendly design with a range of attachments for styling versatility—whether you’re looking to define curls, add volume, or achieve sleek, straight blowouts. The included attachments, like the wide-tooth comb and flyaway tool, are game changers for taming frizz and enhancing shine. It’s a great choice for those who want professional-level styling results and various styling options in one tool.

Who It's For: Like the Dyson, the AirLight Pro will work for all hair types because you can modify the heat and speed settings. Unlike the Dyson, it features a high-tech design that connects to your smartphone so you can save your customized settings. If you value precise control over your styling experience, the built-in Bluetooth connectivity and accompanying app allow users to specifically pick their heat and wind speed in 10-15% increments, making it a dream for those with delicate or heat-sensitive hair types. Whether you have fine, thin hair like me or you’re simply seeking a more tailored approach to your blowout routine, the AirLight Pro’s smart features help achieve salon-quality results without sacrificing hair health.

So, Which Dryer Wins?

Attachments

Winner: Dyson Supersonic

The Dyson Supersonic Hair Dryer takes the lead when it comes to attachments. It has five specialized attachments and is designed to cater to all hair types and textures. The diffuser features long prongs that enhance curl and wave definition, while the wide-tooth comb is perfect for shaping and adding volume to curly and coily hair. My favorite is the flyaway extension, which smooths hair to a silky finish sans frizz and is ideal for longer locks like mine. The gentle air attachment creates a softer, more delicate airflow for those with finer strands or sensitive scalps. Finally, the standard concentrator is great for achieving sleek, straight blowouts or curls, especially when paired with a round brush.

By comparison, the AirLight Pro comes with a concentrator and diffuser. While I appreciate the autodetect feature, which optimizes airflow and temperature based on the attachment, the limited selection of styling options left me wanting more.

Settings

Winner: L’Oreal Professionel AirLight Pro

The AirLight Pro’s high-tech, customizable design sets it apart.With three manual heat and speed settings, it offers versatile performance, but the real game changer is its Bluetooth connectivity. Paired with the accompanying app, I could fine-tune the heat in 10-15% increments and adjust the wind speed precisely. As someone always mindful of heat damage, I really appreciated the lower heat and wind settings. I also loved that the app saves my custom settings, allowing multiple user profiles or personalized styling preferences without disrupting my go-to selection. I even created a profile for my sister so our preferences wouldn’t interfere.

While the Dyson Supersonic offers three speed settings and four heat options, I wish it offered more precise selections, like the AirLight Pro.

Performance

Winner: L’Oreal Professionel AirLight Pro

The AirLight Pro performed best for my hair needs (I have thin, fine hair and am trying to promote hair growth). Its advanced infrared technology shortened my drying time significantly and minimized heat damage, leaving my hair feeling healthier after each use. The infrared light helps protect hair from exposure and promotes smoother, shinier results, which I noticed right away.

While the Dyson Supersonic also excels at reducing drying time and delivering powerful airflows, it didn’t quite match the AirLight Pro’s ability to balance speed with hair health. For my hair type and priorities, the AirLight Pro features a technologically advanced design that offers a fully customizable experience.

Final Verdict?

Ultimately, my favorite is the AirLight Pro because of its cutting-edge technology and personalization. As someone who tries to only wash their hair twice a week, I feel better knowing the infrared light and settings are working to minimize damage.
